The magic is in the Multi-Touch.
The new Magic Mouse redefines what a mouse should do. In addition to its smooth, seamless top-shell design that acts as one button or two, Magic Mouse features a Multi-Touch surface with gesture support. Scroll vertically, horizontally and diagonally - a full 360 degrees - simply by touching anywhere on the top surface. With a greater surface area for scrolling, you can get around a long timeline in iMovie, through a lengthy web page in Safari or around a set of images in iPhoto more efficiently. You can also swipe through pages in Safari or photos in iPhoto with two fingers. It’s the most advanced Apple mouse ever made.

One or two. Left or right.
The seamless, one-button design of Magic Mouse makes it simple to use, right out of the box. But if you want the functionality of a two-button mouse, that’s easy, too. Just change the configuration in System Preferences. And the ambidextrous construction means Magic Mouse is great for lefties or righties.

Laser tracking engine.
Magic Mouse features a laser tracking engine that’s far more sensitive and responsive on more surfaces than traditional optical technology. That means it can track with precision on nearly every surface with no mouse pad required.

Bluetooth technology.
Magic Mouse works wirelessly with your Bluetooth-enabled Mac. When you combine it with the Apple Wireless Keyboard, the result is an untethered and uncluttered work space. Once you pair Magic Mouse with your Mac, you can enjoy a secure and reliable connection from up to 33 feet away.
